In the meantime , the new region current keeps increasing and expanding towards the night and equator side , and it eventually replaces the original region current , so the polar cap returns to a state as original with a dawn - dusk electric field 與此同時,新生的區電流不斷增強并向夜側和赤道方向延伸,最終取代原區電流,相應極蓋區又恢復到原來的晨昏電場狀態。

The anomalous fac pair creates a transient dusk - dawn electric field over the polar cap , tailing behind the original region current and drifting towards the night side until it falls into oblivion 該異常場向電流對在極蓋區形成瞬間昏晨電場,尾隨原區電流向夜側方向漂移直至湮沒。

Because the crystalline cellular structure holds a higher vibration , global warming will continue and in time melt both polar caps of all ice 因為水晶細胞結構持有一個更高的振動,全球變暖將繼續,并在不久溶化南北極的全部冰帽。

There is water on mars . more specifically , there is ice in and on the ground ( especially at the polar caps ) and water vapor in the atmosphere 火星上有水。更確切的說,地表和地下的冰(尤其在冰帽里)以及大氣中的水汽。

Oddly , the region lies near the martian equator and not near either of mars ' frozen polar caps 很怪異的,這個區域緊鄰著火星赤道而非位于冰冷極區的附近。

Zuber and her colleagues also analyzed mars ' s much larger northern polar cap 尤伯和她的同事也分析了火星上要大得多的北部極地冰冠。

This year , shanshan ' s dad was a pilot on flights over the polar cap 今年,姍姍的爸爸成為了飛兩極冰帽的航班上的飛行員。

The polar caps are now in a warmer climate where they begin to melt 極圈現處在它們開始融化的較熱的氣候里。
